RAIL travellers are being warned of disruption on services between Newport and Cardiff, as well as to London, over the Bank Holiday weekend.

Replacement buses will run between Newport and Cardiff from Saturday, August 26, until 1pm on Bank Holiday Monday, August 28 as a result of electrification on the Great Western line.

Services will then continue as normal from Cardiff to Swansea.

Meanwhile, trains to London will start at Newport and will be diverted via Patchway instead of Bristol Parkway as a result of upgrade work in Bristol.

Network Rail's managing director for Wales Andy Thomas said: "We’re working over the bank holiday weekend to prepare for the new fleet of bi-mode trains.

"We are working closely with Arriva Trains Wales and Great Western Railway to improve services for passengers.

"The new Intercity Express trains will run on electric and diesel, provide extra seats with more legroom for passengers, and benefit from improved on-board wifi.

"We would like to thank residents and passengers for their patience and would urge everyone to check before travelling over the bank holiday weekend."

And Arriva Trains Wales customer services director Lynne Milligan said: "All customers should look to plan ahead before travel so they are aware whether there is an impact on their journey."

The work includes demolishing half of Splott Road bridge in Cardiff and raising Adamsdown footbridge, known as 'Black Bridge'.

Services will continue to be reduced until Sunday, September 3.
